FLUE OR CHIMNEY CAP.

SPECIFICATION formingpart Of Letters Patent N0. 653,732, dated July 17, 1900.

Application filed April 21,1900. Serial No. 13,760. (No model.)

To (all whom it may concern:

Be it known that LFREDRICK FIOKENSCHER, a citizen of the United States of America, residing at Lock Haven, in the county of Olinton and State of Pennsylvania, have invented certain new and useful Improvements in Flue or Chimney Caps, of which the following is a specification.

My invention relates to chimney or flue caps.

The object of the present invention is the provision of a cap of simple and inexpensive construction adapted to be readily applied to the top of a chimney or flue which will effectually protect the bricks at the top of the chimney by preventing rains from having access to the mortar between the bricks, thereby obviating the resultant loosening of the bricks by the washing action of the Water and preserving the chimney or flue.

I accomplish the foregoing object by the pro vision of a cap of novel construction which is impervious to water and adapted to shed it easily and which can be secured on the top of an ordinary flue or chimney by mortar or cement.

The invention is set forth in detail hereinafter and the novel features recited in the appended claims.

In the accompanying drawings, Figure 1 is a sectional elevation of an ordinary brick chimney, showing the sectional form of my improved cap in position thereon; Fig. 2, a plan view of the cap shown in Fig. l; and Figs. 3 and 4-, views similar to Figs. 1 and 2, respectively, but showing the cap when made in a. single piece.

It is a common trouble with chimneys that their upper or top bricks become loosened in the course of time by the washing out of the mortar by rains. The loosened bricks not only impair the efficiency of the chimney, but often fall down Within it.

The present invention is designed to prevent the rain from gaining access to the mortar between the upper bricks.

Referring now to Figs. 1 and 2, the numeral 1 designates an ordinary brick chimney, and 2 is my improved cap. This cap is preferably constructed of terra-cotta or fire-clay, having a glazed upper surface to prevent the penetration of water and to facilitate shedding of the rain. The cap is preferably square in shape, having the faces 3, which incline downwardly from a square opening 4, extending through the center of the cap, of sufllcient size to permit free egress of the smoke rising in the chimney or flue. At the four sides of the cap are downwardly-extending flanges 5, which embrace the upper bricks of the chimney or flue and assist in holding the cap in position thereon. Corresponding to the downwardly-inclined faces 3 on the top of the cap are upwardly-inclined faces 6 on the bottom thereof, between which and the top of the chimney is laid mortar or cement 7, which is placed on the chimney just previous to the placing of the cap in position. It will be observed that the provision of the upwardly-inclined faces 6 in connection with the cement or mortar prevents any lateral displacement of the cap independently of the flanges 5. The cap is made in two halves or sections 8 and 9, the section 9 being provided with dia= metrically-disposed ribs 10 on opposite sides of the opening 4 and at the meeting edge 11 of said section, while the section 8 has curved flanges 12 arranged similarly to the ribs,which take over or engage the said ribs. This sectional construction is of particular advantage where the cap is to be used on a large chimney, as it facilitates the handling and placing of the cap. It will be observed that the curved flanges completely cover the joint of the two sections and prevent the entrance of any rain or moisture between them, while at the same time keeping them tightly together.

In Figs. 3 and 4 I have shown the cap as constructed in a single piece, as I find this often desirable on small chimneys. The construction is similar in all respects to that shown in Figs. 1 and 2, except that the sectional construction with the ribs and flanges is not employed.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The combination with a flue or chimney, of an open cap therefor, provided with flanges at its sides which embrace the sides of the chimney and having its bottom inclined upwardly from the center of the cap, and mortar or cement interposed between theinclined bottom and the top of the chimney.

2. A chimney or flue cap comprising sections placed end to end in continuation of each other and at their meeting edges provided with a connection consisting of a rib on one section and a flange on the other section which takes over and looks with the rib, thereby lockin g the sections together against relative displacement.

3. A chimney or flue cap comprising sections, each of which has an inclined top and flanges at its sides which embrace the sides of the chimney and also. provided with a cutout portion at its center, said sections being placed together, end to end, in continuation of each other and one of which is provided 15 with ribs on its top and on opposite sides of the cut-out portion and the other section having flanges arranged similarly to the ribs and taking over and locking therewith, whereby the sections are held together and their joint 20 protected from moisture.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
